Palm-leaf marshmallow Althaea cannabina
ABOUT
Althaea cannabina, commonly known as palm-leaf marshmallow, is a perennial herbaceous plant. It is characterized by its palmately lobed leaves, which are similar to those of the cannabis plant; hence, the species name "cannabina". The leaves are greyish-green and covered with a soft, velvety down. The palm-leaf marshmallow bears dainty, five-petaled flowers that are light pink to pale purple in color. These blooms typically cluster along the upper parts of the stems, creating a delicate, feathery effect as they sway in the breeze. Each flower has a darker center with prominent stamens. The stems of the plant are erect and branched, with a texture that is both tough and flexible. They are similarly covered in downy hairs that give them a soft, slightly fuzzy appearance. The overall shape of the plant is loose and airy, with its stems and leaves creating a fine-textured silhouette. Despite its common name, the palm-leaf marshmallow does not possess edible parts like the true marshmallow plant, which has roots historically used to create a treat that inspired today’s marshmallow confections. The plant's aesthetic qualities make it a pleasing addition to gardens, especially in naturalized or wildflower settings.

WaterPalmate-leaf Marshmallow plants require consistent moisture, especially during their growing season in spring and summer. Water them thoroughly once the top inch of soil feels dry to the touch, which could mean watering every few days during hot periods or less during cooler, wetter periods. A good method is to use a watering can to gently soak the soil around the base of the plant, avoiding wetting the foliage, which can promote disease. On average, they may need about 1 to 1.5 gallons of water per week, depending on weather conditions and soil type.
LightPalmate-leaf Marshmallow thrives in full sun to partial shade locations. The plant prefers to be in a spot where it can enjoy at least six hours of direct sunlight daily, but it can also tolerate some afternoon shade, especially in hotter climates. Too little light can lead to leggy growth and fewer flowers.
TemperatureThe Palmate-leaf Marshmallow can withstand a wide range of temperatures but grows best when the temperature is between 60-85°F. It can survive minimum temperatures down to around 30 to 40°F but should be protected from hard frosts. In hot climates, it appreciates protection from the extreme afternoon heat.
PruningPruning Palmate-leaf Marshmallow helps maintain its shape, remove dead or diseased growth, and encourage bushier, more floriferous plants. Prune in late winter or early spring, cutting back the previous year's growth to healthy buds. Deadheading spent flowers can also promote further blooming.
CleaningAs needed
SoilThe best soil mix for the Palm-leaf Marshmallow (Althaea cannabina) is well-draining with plenty of organic matter, such as a blend of loam, peat, and sand. The soil pH should be neutral to slightly alkaline, around 6.0 to 7.5. Amend the soil with compost to enhance fertility.
RepottingPalm-leaf Marshmallow (Althaea cannabina) should be repotted every 2-3 years to replenish the soil and accommodate root growth. It's best to repot in the spring, just before the growing season begins.
Humidity & MistingPalm-leaf Marshmallow (Althaea cannabina) is tolerant to a range of humidity levels but thrives best in moderate humidity conditions. It does not require high humidity and can grow well in typical outdoor environments where the humidity is not excessively dry.
Suitable locationsIndoor
Ensure bright light and ample space.

Life cycleAlthaea cannabina, commonly known as Palm-leaf Marshmallow, begins its life cycle when seeds are sown in the soil and germinate, usually in spring. After germination, the seedlings grow into vegetative plants, establishing a rosette of leaves and then elongating with a stem that produces palmate-lobed leaves. As the plant matures, blooms appear in the summer, with small pinkish flowers that are attractive to pollinators. Following pollination, the flowers develop into seed pods that, once dry, release seeds to the environment. These seeds can remain dormant in the soil until conditions are favorable for the next cycle of germination. The plant is a perennial species and can regenerate from the rootstock if conditions are not suitable for seed germination.
PropogationPropogation time
Spring-early summer
The most popular method for propagating Althaea cannabina, commonly known as Palm-leaf marshmallow, is by seed. To propagate Palm-leaf marshmallow from seed, one should sow the seeds in late winter to early spring. The seeds need to be planted in well-drained soil at a depth of about 1/4 inch (approximately 6 millimeters) and spaced several inches apart to allow for proper growth. The soil should be kept moist but not waterlogged, and the seeds typically germinate in 21 to 28 days if kept at room temperature around 70°F (approximately 21°C). Once seedlings have developed and are strong enough, they can be transplanted to their final location outdoors after the risk of frost has passed.
